Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00499 - 0.02097), b=3.05 (2.86 - 3.24), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.4   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; Fec= 3 million).
Vulnerability (Ref. 59153):  High vulnerability (60 of 100) .
Price category (Ref. 80766):   Very high.
